The human residents of Blue City live unaware they are at the mercy of beasts who can shapeshift, regenerate and resurrect. The epicki, nocturnal beings who survive on blood, are the ruling race. They head the Chapter, a secret governing body in the city, and report only to the Gearleok, a triumvirate of creatures who do as they please and toy with all. Blue City is painted red as hounds vie with the epicki for power, hunters undermine control and a lethal plague approaches from the West. A Chapter agent is embroiled in the ensuing carnage when he is assigned to protect a human female, amidst fears of the downfall of Blue City. Agent Garrett soon finds that bloodlust cannot be curtailed while nature, loyalty and reality blur in various factions that favour survival above all else.
